Abstract

In this paper, a new type of dual-channel triangular planar capacitive sensor is proposed, which can overcome the problems of small dynamic detection range and low sensitivity in nondestructive testing (NDT) applications. By establishing a three-dimensional simulation model of the sensor, the influence of structural parameters such as excitation electrode, shielding electrode, protective electrode, and thickness of substrate on its various performance indicators was systematically analyzed using ANSOFT finite element analysis (FEA) software. By studying the corresponding relationships between different performance indicators and structural parameters, a mathematical relationship between penetration depth and electrode structural parameters was established, and the general design principles and methods for dual-channel triangular planar capacitive sensors were determined. Finally, through experimental verification, it was proven that the theoretical analysis results were consistent with the experimental results, providing a theoretical basis for the optimization design and application of the dual-channel triangular planar capacitance sensor.
